lanceolate acuminate sepals and petals are of a light rose-pink colour, and the 
ovate shortly acuminate lip white with numerous radiating rose-coloured lines 
extending throughout its entire length. The large fleshy crest is marked in 
the same way, and the column is white with some pink lines on the face 
and some splashes of the same colour on the back, and also on the fleshy 
wings. 
This élégant species is dedicated to Madame Linden, wife of M. Lucien 
Linden. 
The section Euzygopetalum contains a number of very handsome species, 
of great horticultural value, though several of them are very nearly allied, 
and difficult to separate satisfactorily. Z. intermedium , crinitum , Mackayi , and 
brachypetalum , for example, are sometimes confused in gardens, or, in other 
words, are found doing duty for each other, and it is not al way s easy to find 
botanical characters to separate them absolutely. Z. maxillare is another hand¬ 
some form, easily recognised by its gigantic crest. Z. Murrayanum , from the 
Organ mountains, and its near ally Z. Burkei , from Roraima, are also suffi- 
ciently distinct, as is Z. Sanderianum. The three recent additions to the group, 
however, introduce a greater amount of variety than would a priori be expected. 
Z. caulescens has a remarkable caulescent habit which is quite novel in the group. 
Z. Jorisianum introduces a novelty of another kind, in its three-lobed beautifully 
fîmbriate lip ; while Z. Lindeniae has pecularities both in shape and colour. 
There are also two or three very useful hybrids in the group, of which 
we may mention Z. X Sedeni and Z. X Clayi , while Z. X leopardinum is a beautiful 
little form whose parentage remains doubtful. It has been supposed to be some 
one of the above-named species crossed with Colax jugosus , a supposition which 
may ultimately prove correct. Zygopetalum cnnitum , however, crossed with Colax 
jugosus , yielded the handsome bigener called Zygocolax X Veitchii , which is not 
identical in the shape of its pollinary apparatus, and thus renders confirmation in 
the former case necessary. R. A. Rolfe.
